Abstract. To determine the degree of influence of meteorological factors on long-term gravimetric measurements, the reaction of the Earth's crust to the change in atmospheric pressure in the frequency range corresponding to the time of stacking of information of one and a series of readings of the gravimeter was evaluated. In the course of experimental work, the effect of a change in the level of microseismic oscillations due to a change in atmospheric pressure was revealed. The experimental results of long-term observations at the measuring gravimetric point confirm that the level of microseismic oscillations is much lower at elevated atmospheric pressure. With a decrease in atmospheric pressure in the spectrum of microseismic noise, the greatest increase in amplitudes occurs in the frequency range 0.05–0.5 Hz. The necessity of eliminating diurnal variations in the level of microseisms due to a change in the ambient temperature is proved.

 

Keywords: long-term gravimetric observations, microseismic oscillations, baric and temperature effects on the level of microseisms, estimation of the effect of microseisms on long-term gravimetric measurements.
